King Abdullah of Jordan has promised a "relentless war" against ISIS after the gruesome murder of a captured Jordanian Air Force pilot. Two Islamists on death row in Jordan were executed this morning in apparent response, and the pilot's father has called for more. But how united is Jordan?

A Jordanian pilot has been captured by ISIS after his plane went down in northern Syria. The news has Jordanians worried for their countryman and rallying around the anti-ISIS mission like never before.

Hundreds of thousands of Syrians have fled their war-torn country in hopes of safety in neighboring countries. But for Syrians of Palestinian descent, they find they're not as welcome in neighboring Jordan as native Syrians.

More Syrians are trying to leave their war-torn nation. Many head for neighboring Jordan, but as The World's Matthew Bell discovered not all are welcome. The Jordanian authorities try to turn away Syrians with Palestinian IDs.
